The purpose of this study is to present a reflective review of the earth and universe units from the revised elementary curriculum of 2007-2015 and suggest changes in the 2022 revised curriculum. For this purpose, we conducted an FGI with earth science educators and elementary school teachers regarding the content elements and system, the achievement standards and inquiry activity composition, and the vertical and horizontal curriculum connectivity. Free response and weighted hierarchical analysis items were incorporated into the FGI to ensure logical consistency of the inductively derived improvement. This analysis revealed that the composition of units by grade group had been unevenly distributed among each of the "earth systems" until the 2015 revised curriculum was finalized. Furthermore, the basic concept was still insufficient. We suggest that achievement standards centered on the learning content and skills must state specific scientific core competencies, and inquiry activities should include rigorous critical thinking, student written responses, and student inquiry and analysis. In the hierarchical analysis items, FGI emphasized the inclusion of essential content elements rather than reduction of content elements, understanding-oriented concept learning rather than interest-centered phenomenon learning, basic concept division learning before integration between subjects, and expanding vertical-horizontal connectivity rather than repeating and advancing learning. There is a limit to the generalizing the suggestions proposed in this study to the common opinion of elementary earth science experts. However, since the main vision of the 2022 revised curriculum is to gather opinions through educational entities' participation in a variety of educational subjects, it is suggested that our results should be incorporated as one of the opinions proposed for the 2022 curriculum revision.

This research is a survey study on students' attitude toward a class employing small group discussion and presentation by the method of free-listing. Participants in this study were students who registered in the course of Mathematical Logics and Writing during 2011 and 2014. Senior students who took the course of theory of mathematics education previously usually registered the course. The class for this course used to be designed as a class adopting group discussion and presentation. Main theme of this research is not to demonstrate some theories or hypothesis on teaching and learning, but rather to inquire students' attitude toward a class employing the constituents first and then through analyzing the results of this study to find practical ideas and strategy for design and implementation of a class which brings cultivation of students' understanding, communication and moreover writing in mathematics. Since the survey was given in the $8^{th}$ week of this class, participants of this research could be expected to have more concrete idea for positive or negative aspects of the classes employing these constituents. We compared both research results of 2011 and 2014 to view any changes in students' attitude. Research results are follows. Students began to think that group discussions and presentation bring out better learning to them. Not to give students psychological burden of discussion and presentation, instructors need to provide comfortable atmosphere through arranging suitable grouping and enough time for discussion. Moreover, simple evaluations criteria for group discussions and presentation should be well structured and more concrete guides for them are required to make students to feel comfortable and to concentrate on the given subject for discussion.

This study attempts to reconsider the significance of political economy as a theory of knowledge and/or a method for explaining the convergence of broadcast and telecommunications. It is going to suggest what the domains of political economy should be in the future by both highlighting the characteristics and blind spots of previous studies and drawing some distinctive features of a new media environment. The principals and recent research trends in political economy are reviewed in order to make clear that the historical totality as a meta-framework of political economy needs to be reexamined in the era of convergence. Although the scope of political economy has been limited to criticize the structure of media ownerships, the study emphasizes the importance of media consumer theory. It also discusses the problems of free market theory, distortion of active media audience theory, and limitations and creative tension of audience commodity. Finally, this study stresses the significance of audience-oriented policies in order to make approach to practical sides of media politics.

The meaning of the characteristics of formative expression in contemporary residential architecture is flowing elements as important means to inbreathe emotional feeling of movement and as automatic and positive wats of expression. So the purpose of this study was to analyze the characteristics of formative expression in contemporary residential architecture, and to plan residential design linked with this kind of concept. For this study, analysis of case studies were used and the cases were selected in contemporary residential architecture which were represented having formative expressions since 2005. The major results found that the characteristics of formative expression were ex-center, reiteration, dispersibility, diagonality, plasticity, non-linearity, and deconstruction. In addition to that, we derived various methods expressing the formative characteristics, which were mass transformation, plan variation and composition element transformation. Summing these results up, the various characteristics of formative expression in contemporary residential architecture are understood as the results of the free modeling will of architects fulfilled with the spirit of inquiry and experiment to escape from the standard architecture in order to differentiate themselves.

This study aimed to explore how to characterize the earth science inquiry in schools in terms of science teaching interaction and constructivist teaching practice. The constructivist teaching practices were analyzed with Reformed Teaching Observation Protocol (RTOP) in three aspects including (1) student oriented class implementation, (2) subject knowledge and representation, and (3) classroom communication. Fourteen earth science classes were observed and scored with RTOP. The class was evaluated to be transitional stage in terms of constructivist teaching, e.g., moving toward student-centered teaching practice. Especially, Korean teachers tend to lean their classes more on propositional knowledge than procedural knowledge. To interpret science teaching interactions, an earth science teacher with a RTOP top rank was selected. Her class was then videotaped for detailed analysis. I adopted the analytical framework of communicative approaches and discourse patterns among the five aspects of interactions presented by Mortimer and Scott (2003). It was found that this earth science teacher used more authoritative patterns than the dialogic. In addition, she used IRE discourse pattern more frequently. Interestingly, teachers interacted with their students more frequently in the form of repeated (or IRE chain pattern), that is IRFRF (teacher initiation-student response-teacher feedback-student response-teacher feedback) in the context of dialogic communicative approaches, while simple IRE occurred in an authoritative approach. In earth science classrooms, typical interaction may well be constructed in the form of IRFRF chains to allow students free conjectures and abduction.

Brief hypnotherapy with daily self-hypnosis was used to a 20-year-old male patient who had severe warts on the fingers of both hands for 6 years. He had had several dermatological treatments, including attempts to remove the warts with topical chemotherapy, but the warts had always recurred. During the hypnotic session, it was suggested that the warts would begin to feel cool and disappear with imaginary laser. He responded well to ideosensory suggestions and was free of the warts within 5 sessions. Inquiry after 7 months revealed that no recurrence had taken place. Finally, it is stimulating to think that harmony between mind and body involving cell-mediated immunity can intervene in conditioning the course of the skin diseases.

For the past few decades functionalism have dominated the epistemological arena in organizational science. However, the positivist-inspired movement of functionalism have proved inadequate for explaining the radical transformations of organizations. During the last decade dialectical theory has been starting to be heard. This paper identifies the dialectic as the unifying principle of a broad and diffuse tradition of thought. Beginning with a excavation of the philosophical foundations of dialectical theory in the thought of Kant, Hegel, and Marx, this paper goes through the various twists and the turns of the dialectic in the major twentieth-century movements of neomarxism, phenomenology, and critical theory. Also, this paper presents the implications of the dialectical approach in organization science. The discipline of organization theory has been imprisoned by its functionalism, therefore, stimulating an awareness through which it can begin to set itself free has become imperative. Dialectical theory, be cause it is essentially a process perspective, focuses on the dimension currently missing in much organizational thought, It opens analysis to the processes through which actors carve out and stabilize a sphere to the processes through which actors carve out and stabilize a sphere of rationality and those through which such rationalized spheres dissolve.

The purpose of this study was to examine the interaction strategies used by typically developing boys and girls in their dealings with young children with ADHD in free play situations in inclusive classes. This was done in order to gain an in-depth understanding of the meaning of their interaction strategies. The subjects were 52 typically developing children (comprising 27 boys, 25 girls) and 3 young children with ADHD. The findings were as follows : First, the overall frequency of interaction strategies with the young children with ADHD was greater among the young female children (n = 372) than the young male children (n = 298). Second, when the utterance strategies of the male and female children were sub-categorized, both the male children (79.5%) and the female children (57.0%) mostly made use of avoidance strategies, one of the typical withdrawal strategies. Third, the interaction strategy of control represented 42.0 percent and as such was identified as the most prevalent interaction strategy utilized by the young male children studied. In the case of the young female children, obliging strategies were the most common interaction strategies representing 33.1 percent of the total used. In the light of the findings yielded from this study, some educational recommendations are provided.

This study examines the emotional undercurrents of individual investors. Earlier finance theory was based on the assumption that investors would act rationally. According to the findings, it is the investors' collective expectations and anxieties that have an impact on their investment fortunes. This necessitates a high level of emotional stability on the side of the investors. Investors must have a firm foundation in financial literacy to have the requisite level of emotional stability. This study aims to add to existing theory and practice by analyzing whether investors who have received business-related education are less emotional than those who have not. For the survey inquiry of individual investors, 'fear' and 'love' are considered among the emotional undercurrents of individual investors. The research is based on a survey of 875 individual investors in India, 342 of whom had a business background and the others have none. It has been discovered that no investor, regardless of their level of business education, is emotion-free. Investors with and without a business education display emotional stability in many behavioral aspects of fear and love to varying degrees.

This inquiry was conducted to develop DeNOx catalyst for LNT. In order to develop appropriate catalysts, four catalysts, which do not use PGM (Platinum Group Metal), were carefully selected : Al/Co/Mn, Al/Co/Ni/Mn, Al/Co/Mn/Ca, Al/Co/Ni mixed metal oxides during preliminary experiments. Also, XRD, EDS, SEM, BET and TPD tests were carried as well to evaluate both physicochemical properties of such four catalysts. As a result of the experiment, four catalysts were composed of spinel-shaped crystals and had more than enough pore volume and size to have oxidation-reduction reaction of NOx gases. Additionally, through TPD test, all four types of catalysts were proved to possibly have an oxidation-reduction acid site and NO oxidation activities similar to commercial catalysts. Based on the results above, if we have further change in the composition components and active ingredients according to the catalysts that were chosen in this investigation, then we are more welcomed to expect to have an enhanced DeNox catalyst for LNT.
